Miltiadis Stouras


Hello, I'm Miltos! I'm a PhD Student at EPFL's Theory Group where I am advised by Ola Svensson.

I work on modern algorithm design, with research interests spanning both fundamental theory and emerging applications. I focus on designing algorithms under uncertainty, including settings like stochastic optimization, online decision-making, and data-driven algorithm design. More recently, I have explored applications in retrieval-augmented generation (RAG) and AI for education, and I'm also excited about reasoning with large language models and inference-time scaling.

Before joining EPFL, I did my undergraduate studies at the National Technical University of Athens, where I completed my master's thesis with Dimitris Fotakis. During that time, I co-founded White Noise, the space engineering team of NTUA, and gained some industry experience working as a Software Engineering Intern at Amazon.
